Operations & Integration
Flexible operating models and seamless integration into existing IT infrastructures
Back to OverviewOperating Models - Flexible and Future-Proof
All models use the same code base - a later change is possible at any time. Choose the right operating model for your requirements.
| Model | Deployment | Typical Use Case |
|---|---|---|
| SaaS | ISO 27001-certified data center in Germany, operated by UPONU | Quick implementation without own operation |
| Private Cloud | Container cluster (Kubernetes) in customer environment | When data residency or internal policies exclude cloud |
| On-Prem | Same container stack as in-house installation | Air-gapped networks or regulatory requirements |
All models use the same code base - a later change is possible at any time.
